Margo, I tried to email you personally about your success rate with intact perineii(?) and shoulder dystocias but it got returned. so I'm posting to the list instead. What I don't quite get the grasp of is your "on hands and knees" positon for the paatient with shoulder dystocia. As much as I try, and I have tried (and even discussed it with my partners), I can't envision that position giving more room for a shoulder dystocia since every response to the list has stated that it is a bony dystocia, not a soft tissue problem. I'm having trouble understanding the mechanics behind a change in the mother's positon and a change in the orientation/size of the bony pelvis which is restricting the delivery of the infant's shoulders. In case this is misconstrued....this is an honest question and not sarcastic. Anything I can learn to help a patient is worthwhile. Also, any references on this technique? Thanks for any light you can shed on my biomechanical dilemma.

The American Medical Association is no longer designating CME hours for AMA Category II CME credit. However, physicians themselves may self designate learning activities as Category II CME credit hours if they feel it is of sufficient educational merit and meets the formal definitions of continuing medical education. OBGYN.net believes these interaction in this forum meets these criteria. For further information see the AMA web site.
